If the Sampler Info node finds that the pixel being rendered is on an evenly numbered row (in the Y direction of the frame) then it assigns a random color to the pixel, but if the pixel is on an oddly numbered line it assigns the color black to the pixel.

• 如果采样信息节点找到被渲染的象素是在一个偶数的行（在帧上的Y向上），然后它赋予一个随机的颜色到象素上，但如果这个象素是在奇数行上，这将赋予一个黑色去象素上。
